Abstract

The invention provides an operation control method, a compressed air heat exchange system and a storage medium. The operation control method of the compressed air heat exchange system comprises the following steps: in response to an obtained set temperature, a motor in a supercharging expansion module is controlled to operate, and an air return temperature is acquired; and according to the relation between the set temperature and the air return temperature, the rotating speed of the motor in the supercharging expansion module and the rotating speed of a fan are controlled. Through execution ofthe technical scheme, on the one hand, the fresh air feeding is realized to facilitate improvement of the quality of air in rooms; on the other hand, the air is directly adopted as refrigerants to replace compound refrigerants in related technologies; through combination of the operation of a compressor and an expander, the refrigerant setting cost can be saved, and the environment harm is reduced; and on the third hand, through arrangement of the rotating speed of the fan matched with the rotating speed of the motor, the air pressure in the rooms meets the use demands of users.

Description

Technical field [0001] This application relates to the field of household operation control, and in particular to an operation control method, a compressed air heat exchange system and a computer-readable storage medium. Background technique [0002] In related technologies, household compressed air heat exchange systems usually adopt vapor compression refrigeration, that is, using the phase change latent heat of the refrigerant to remove the cold or heat in the room, but it has the following defects: [0003] (1) Most refrigerants are harmful to the environment, such as the greenhouse effect and ozone layer holes. [0004] (2) If users stay in an air-conditioned environment without fresh air for a long time, their health will be affected. Summary of the invention [0005] This application aims to solve at least one of the technical problems existing in the prior art or related technologies. [0006] For this reason, one purpose of this application is to propose a new operation contro...
